The Patent Trial and Appeal Board (“PTAB”) issued Final Written Decisions regarding Cisco’s U.S. Patent Nos. 6,377,577 (the “’577 Patent”) and 7,023,853 (the “’853 Patent”) on May 25, 2017 and U.S. Patent No. 7,224,668 (the “’668 Patent”) on June 1, 2017. The PTAB found the ’577 and ’668 Patents invalid but upheld the validity of the ’853 Patent. The Inter Partes Review (“IPR”) proceedings were brought by Arista Networks in retaliation to Cisco’s accusations of infringement brought in multiple venues, including at the U.S. International Trade Commission (“ITC”), which had just a few weeks earlier upheld the validity of these very same patents and determined that Arista infringed the ’577 and ’668 Patents, and issued exclusion and cease and desist orders accordingly. Since the IPR decisions issued Arista has filed a petition asking the ITC to suspend its limited exclusion order regarding the ’577 Patent based on the PTAB’s decision and is expected to file a similar request with respect to the ’668 Patent. On the other side, Cisco plans to appeal the PTAB’s decisions to the Federal Circuit. The uncertainty created by these inconsistent outcomes is an issue for patent owners, and it will be interesting to see how these cases are resolved. In addition, this case shows that even though the ITC does not stay its investigations for IPRs, IPRs may still impact ITC proceedings.
